Early testing by GPS technology leaders, Garmin and Trimble Navigation, demonstrated that LightSquared‘s technology would likely interfere with Global Positioning System (GPS) receivers, degrading their performance in the best case scenario and completely jJamming GPS receivers in the worst case scenario. The Department of Defense, FAA, DHS, NASA, DOI, DOT, DOC, and the Professional Land Surveying and Engineering professions, have all expressed serious reservations in regards to this plan by LightSquared, LLC to build 40,000 ground stations in the U.S. that could cause widespread interference to—GPS signals. : This network of ground stations will transmit signals within the L—bandfrequency immediately adjacent to the GPS L1 frequency at more than onebillion times the strength of the low—power GPS signal from space. Furthermore, each mobile phone using LightSquared‘s wireless service would potentially become a portable GPS jammlng device by jamming GPS receivers in its immediate vicinity. : : t High—precision GPS equipment used by Land Surveyors. and other geomatics professionals costing thousands of dollars per receiver would be more adversely affected than the consumer GPS devices given their inherent design. Literally, tens of thousands of high—precision GPS receivers are used in the United States. GPS technology has transformed the way we build and manage our infrastructure, adding a tremendous level of efficiency to the design, construction, and maintenance of roads, bridges, commercial properties, residential subdivisions, parks, farms, golf courses, etc. GPS has become an essential tool for design professionals and it is imperative that these GPS signals are not Jeopardrzed by broadband technology. This situation has the potential of becomlng a tremendous public safety issue and an economical disaster not only for New Jersey, but also for the United States as a:whole. The members of the New JerseySociety of Professional Land Surveyors urgeyou to reject the LightSquared application until. such: time. that all tests: conclusively demonstrate there is no risk of'interference.’ Sincerly, / PH)— 11214 785 —4.7.6 6E @j ZAx 744728522 L w. £LpARLE Dfdr‘)p': 7 . | pw,fl/fljsVitL: E Pfi /"’4-/7
